8 Claims.

The invention hereinafter described is an improvement in smoking pipe structures provided with an arrangement for controlling the firing of tobacco therein and cooling, drying and removing undesirable ingredients from the smoke produced thereby.

v The present invention is a continuation in part of the invention shown and described in my copending application Serial No. 260,176, filed March 6, 1939.

It is an object of the present invention to provide a pipe structure having incorporated therein a combination of members whereby the firing of tobacco can be controlled to produce a smoke suiting the taste of the user of the pipe and which smoke is cooled and has moistures, tars, heavy oils and like distasteful ingredients removed therefrom before reaching said user.

Another important object of the present invention is to provide an economically produced and serviceable filter for pipe structures which can be quickly and simply conditioned for reuse from time to time as is found desirable.

A further object of the present invention is to provide a pipe structure which is economical to produce and which can be readily assembled and disassembled for cleansing or like attention, yet provides a controlled smoke of a relatively cool and dry character.

In the accompanying drawing and the following description thereon, further objects of the present invention will be in part obvious from an examination thereof I and in part pointed out therein.

In the accompanying drawing:

Fig. 8 is an enlarged side elevational. view of a filter cartridge.

Referring now more particularly to the accompanying drawing wherein like reference characters designate like members, reference character l indicates a mouth-piece having a bore 2 extending longitudinally thereof and having one end portion 3 thereof stepped and threaded upon its periphery for being inserted within and connected to the interior ii of stem portion 5, said interior 6 being threaded for engagement with the threads of said portion 3 and mouthpiece I having the configuration thereof shaped and sized to extend contiguous with and from stem portion 5. Said stem portion '5 is a part of a tubular member 4 made from a lightweight metal such as, for example, aluminum and which has the remaining part 1 thereof shaped to resemble the bowl portion of the usual smoking pipe. The open end of bowl I is enlarged as at 8 and this enlarged portion 8 is threaded upon its interior face.

A firing ring [0, having a centrally located bore 1 i, has the lower portion I l thereof stepped. Said burning ring it is preferably formed from meerschaum and is molded to and within a metallic ring 12, which ring is to be connected to and extends around the periphery of the portion M of the burning ring. Said ring 22 is threaded upon its periphery for ready engagement with the threads 9 of said enlarged portion 8. Ring I2 can thereby be screwed within enlarged portion 8 and burning ring it retained upon the open end of bowl portion l. Said burning ring ID has a series of openings it formed therein extending from bore H downwardly towards the bottom face of ring Ill.

Positioned within bowl portion l is a tubular member I9 having its. inner face forming a series of walls 20 which have a cross sectional configuration of a dodecagon. Said walls 20 are in line with the bore ll of burning ring it and are retained in this position by said tubular member I}! being positioned within an annular flange 35 formed with the bottom interior face of bowl portion I. Said tubular member 19 is formed of a lightweight metal as, by example, aluminum.

Positioned within and completely enclosing the space between said tubular member 59 and the interior side face of bowl portion '6 is a cylindrical filter body l5 formed from a lightweight metal and having a central bore it extending therefilter body I5 is in contact with the interior side face of bowl portion I and due to the frictional engagement of said members, filter body I5 and tubular member I9 are prevented from rotating. Formed through filter body I5 in a. longitudinal direction thereof is an annular series of bores I'I, each of which is in line with the bottom end of openings I3 of said burning ring I8 and thereby connects the interior 6 of tubular member 4 with said bore Ii of burning ring I8.

Inserted within each of said bores I1 and frictionally retained therein by contact with the side walls of said bores are paper cartridges I8. Said cartridges I8 are formed of wound absorbent paper and shaped for being readily inserted within a bore I'I. Said filter body I5 may also be formed from brier-wood or meerschaum and the absorbent filter cartridge I8 may or may not be used, depending upon the desirability thereof, as found by experience when the filter body is formed from either of these materials.

Formed through the bottom of bowl portion 7 at a point centrally located within said annular flange 35 is an opening 36. Said opening 36 has a tubular member 22 extending therethrough and said member 22 is formed with an annular flange 3| extending substantially perpendicular from an end portion thereof. Said flange 3| contacts the interior face of bowl I around the opening 36 and with the remaining portion of member 22, closes said opening 36. Said tubular member 22 is one of a series of telescopic sections 22, 23, 24, 25, 26 and 21, which tubular sections have lefthand threads 34 formed upon the upper face of the bore thereof. Sections 23, 24, 25, 26 and 21 each have lefthand threads 33 formed upon their periphery for engagement with the threads 34 of the next larger section. In this manner, section 23 is in threaded engagement with the bore of section 22 and likewise, section 24 engages the bore of section 23, section 25 with section 24, section 26 with section 25 and section 21 with section 26. The lower peripheral portion of sections 23, 24, 25, 26 and 21 are formed blank as at 31 to prevent the sections from being completely unscrewed one from the other through their upper open end while, however, each section may be unscrewed from the bore of its next larger section for disconnecting the same when desired, by giving the smaller section a continued lefthand rotation. The periphery of section 22 has righthand threads 32 formed thereon and a cap 2| having a threaded interior face can, by giving the same a righthand rotation, be screwed onto said section 22 and coact with flange 3| for retaining section 22 rotatably within opening 36 and, at the same time, cap 2| closes the bottom open end of the bore of section 22.

Slidably mounted longitudinally of tubular member I9 and extending laterally across the bore thereof is a plate 29 having the edge thereof forming a series of walls 30. Each of said walls 38 is sized, shaped and positioned to slidably contact one of said walls 20 of tubular mem- Said plate 29 is preferably formed from a, piece of metal and has molded thereto a meerschaum cap 38, which cap 38 completely covers the upper face of plate 29. Plate 29 has further formed therewith a cylindrical projection 28, the bore of which is threaded for engaging with the threads 33 of telescopic section 2'! whereby the plate 29 is connected to said series of telescopic sections.

Telescopic sections 22, 23, 24, 25, 26 and 2! are assembled by inserting each section through the lower end of the bore of the next larger section until the threads 33 of the smaller section engage the threads 34 of the bore of the larger section. The sections are of equal length in order that when in their closed position, they will completely nestle one within the other, as

shown in Fig. 3 of the drawing. Section 21 is screwed into plate 29 by rotating the same and the telescopic sections together with plate 29 are positioned through the open end of bowl I and through opening 36 thereof until stopped by annular flange 3|. Cap 2| is then screwed onto section 22 by a righthand rotation thereof and thereby closes the lower end of all of the telescopic sections and thereby prevents any of the sections from being removed through the bottom open end of the bore of any of the sections until the cap 2| is again removed from section 22. Tubular member I9 is inserted within bowl I and positioned within flange 35 of said bowl], thereby encasing plate 29 therein and permitting the same to be longitudinally slidable but, at the same time, preventing the rotation of plate 29 due to the contact of the side walls 38 of plate 29 engaging the interior side walls 20 of tubular member I9.

After inserting a filter cartridge I8 within each of the longitudinal bores I! of filter body I5 until positioned as substantially shown in Fig. 5 of the drawing, said filter body I5 is inserted within bowl portion I. Tubular member I9 is thereby inserted within bore I6 of filter body I5 and rotation thereof prevented by the frictional engagement of these members while, at the same time, retaining tubular member I9 in its vertical position. Smoking ring I 0 is then attached to bowl 1 by the threaded engagement of ring I2 and enlarged portion 8 of bowl 1 until the ring In contacts tubular member I9 for further locking the same in position and, at the same time, presenting each of openings I3 of the burning ring II] to one of the bores I! of filter body I5. Burning ring II], at the sametime, contacts filter body I5, forcing the same downwardly until the lower end of filter body I5 is stopped by engaging the curved inner face 3'! of bowl I. That is, a portion of filter body I5 is restrained from further downward movement by the curved portion 31 and tubular member I9. In this manner, a space is provided within the interior 6 of tubular member 4 below the bottom face of filter body I5.

By rotating cap 2| to the right, telescopic sections 22, 23, 24, 25, 26 and 21 are caused to unscrew one from the other due to plate 29 restraining the rotation of section 21 and the unscrewing of these sections causes the same to extend upwardly until they are completely opened, as shown in Fig. 2. Conversely, by giving cap 2| a lefthand rotation, the telescopic sections will screw one within the other until they are nestled, as shown in Fig. 3 of the drawing. With the telescopic sections in their nestled position, meerschaum cap 38 is positioned within the lower portion of tubular member I9 and at this time, tobacco 40 is placed within tubular member I9 upon said cap 38 until the tobacco is at a point above openings I3 and withinburning ring ID. The user of this pipe at that time, by applying a flame to the tobacco 40 and drawing through longitudinal opening 2 of mouthpiece I, ignites the tobacco. By rotating cap 2| and thereby slightly elevating cap 38, the tobacco is moved upward nearer the top open end of bore II of ring I0 and by so adjusting the position of the burning tobacco,'the amount of oxygen fed thereto through bore H can be controlled. It is a mere matter of experience for the user of the pipe to determine thepoint at which he wishes the burning tobacco to be positioned in order to suit his particular taste. The smoke from the burning tobacco is drawn through openings l3 of meerschaum burning ring l and the meerschaum will absorb considerable moisture therefrom. The smoke then passes downwardly through filter cartridges 18 positioned within bore I? and the heavy oils, tars and further moisture will be removed there-- from due to the absorbent action of the cartridges 58. Filter body it and tubular member 4 being formed of a lightweight metal, will readily conduct heat from the tobacco smoke as it passes by and contacts these members and the smoke is thereby readily cooled. The burning ring H3 having the burning tobacco confined therein and being of a heat insulating material will not conduct the heat to the tubular member 4 and filter casing 45 and, therefore, these members will remain relatively cool.

As the tobacco is consumed, cap 2| is rotated from time to time for progressively advancing plate 29 upwardly through tubular member l9 and thereby retains the burning portion of the tobacco 4-9 at the predetermined desirable position. Plate 25 having meerschaum cap 33 thereon is prevented thereby from becoming gummed, due to the deposits of oils and tars from the burning tobacco being absorbed by the meerschaum cap 38 and, therefore, tubular member 19 is similarly protected and remains free from contaminating substances that would possibly prevent plate 29 from readily sliding longitudinally thereof. Further, the tobacco upon the cap 38 can be moved upwardly until positioned as shown in Fig. 2 of the drawing and thereby consumed down to the last portion thereof.

When the user of said pipe finds it desirable, burning ring H! can be readily removed from bowl '5 and filter body I5 slid upwardly and removed from the interior of bowl l. Filter cartridges Hi can at that time be removed from bore i1, discarded and replaced by new cartridges i8 and the filter casing returned to its position within bowl '6' and burning ring I!) also replaced upon the bowl, at which time the pipe is ready for further use. Filter body l5 with cartridges [8 therein not only filters undesirable ingredients from the smoke passing through bore II, but also cools the same by readily conducting the heat therefrom. Further, the filter body can be used indefinitely simply by replacing the cartridges 18 with new cartridges from time to time.

When filter body I5 is formed from brier-wood or meerschaum, the cartridges l8 can be used therewith but due to the absorbing qualities of these materials, the cartridges 18 are not a necessity. However, inasmuch as the taste of smokers vary, some smokers may find the filter cartridges I8 desirable even when a filter body of brier-wood or meerschaum is used, whereas, others may not require the additional filtering of the absorbent paper of the cartridges.

It is obvious that the foregoing described device can be readily modified or have members thereof varied but any such changes or modifications as come within the scope of the appended claims, I deem to be part of the present invention.
